' SUBIMERSIBLE TOY.

. ble Toys, of which the following is a specificationv This inventionrelates to a submersible toy in the form of a submarine which isactuatedby air pressure supplied from an indiarubber ball and tube. Whenpressure is applied to the ball, air enters the hollow vessel or hull,displacing water which has been reviously admitted, and altering itsspeci c gravity, thus causing .it to rise. Within the vessel is a tubesuitablysituated in which a projectile or torpedo is inserted,

and this torpedo is expelled by the air pumped in or by means broughtinto operation by the air.

. The invention is illustrated in the accompanying drawings, in whichfour alternative constructions are shown.

Figure 1 is a sectional side elevation of one modification in which the"air is held from escaping prior to discharge'by a valve ushed home bythe insertion of a projectile. 4 ig. 2 is a sectional side elevation ofanother modification in which the inner end of the projectile itselfforms the valve, being held the valve seat like the cork in a popgun.Fig. 3 is a sectional side'elevation of anothermodification in which theprojectile is held by adetent against the valve seat until discharged.Fig. 4 is a sectional side elevation of a further modification operatingin a manner similar to that shown in Fig. 3, but differing inconstructive details. In each view the torpedo tube is shown loaded. r

In Fig. 1 the toy consists of a metal hull A suitably weighted to.maintain the same uprightand carrying the torpedo tube B B whichisconnectedby means of tube X and valve Y to the air pressure chamberfor which I use an ordinary indiarubber squeeze Z fitted with anon-return-valve.

E is a rubber bladder which fits over B and is' secured to it at eitherend.

Specification of Letters Patent.

Applicationfiled October 15, 1915. Serial No. 56,050.

D is the torpedo or projectile, which on insertion in the tube B pushesback the valve whdich entersthe valve seat with its forward en a The toyis placed in a pond or tank in which it sinks. On pressure being appliedto the ball Z air passes to the tube B and thence through the holes L tothe bladder E causing it to expand. As more air passes to it, and thespecific gravity of. the toy is I altered, it rises slowly to thesurface of the water. When the pressure in E and B rises to a givenpoint, owing'for example to the bladder E being pressed against the hullA, it becomes 'suflicient to actuate the valve 0 which opens suddenly,moving forward and allowing sufiicient air to pass to expel theprojectile, and then closes, the rearward enlarged end entering thesleeve C under the air pressure as the projectile leaves the tube. Theuse of the double acting valve. C to close the tube B after the torpedoD has been discharged prevents the inrush of water and the suddensinking of the vessel. The valve may be so arranged that there is asmall escape through a notch or port hole in the rear end so that thevessel slowly sinks as E deflates. The bladder E as it is distended maycause a small figure M to risefrom a con ning tower.

In Fig. 2 is shown an alternative construction, in which the projectileD forms a and the detent F frees the torpedo which is discharged underthe air pressure. A valve C serves to cut off the escape of a1r asbefore.

In a further alternative construction shown in Fig. A a float may beprovided in the hollow vessel, which prevents the torpedo from beingexpelled until itdro s with the falling water level in the vessel. Herethe torpedo is held in the tube by a detent F r on a lever G, pivoted atH and having a float P at its free end. As the water level in the vesseldrops, the float Psinksand presently frees the torpedo so that,as'described with reference to Fig; 3, the torpedo is discharged by theair pressure. In thisconstruction the tube B is supported in thehull Aonly at its forward-end, the inner end being open.
